Solar water heating or solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors, a water storage tank or another point of usage, interconnecting pipes and a fluid system to move the heat from the collector to the tank.

Complete system for solar hot water
Compatible with all types of back up boiler
Simple and easy to specify, order and install
Optimises the free energy provided by the sun
Supplies up to 70% of the energy demand for hot water

Velux systems are one of a kind. The solar panels look and fit like a roof Window, comply with all government regulations and energy initiatives, and most importantly are cost effective and affordable.
Velux solar systems are produced with premium quality materials, focussing on high performance, design, trouble-free installation and outstanding durability. The development of the solar collector (the Velux solar panel) is based upon many years of rigorous testing and experience, enabling Velux to select the ideal materials for roof integrated solutions.

Biomass, a renewable energy source, is biological material derived from living, or recently living organisms,[1] such as wood, waste, and alcohol fuels. Biomass is commonly plant matter grown to generate electricity or produce heat. For example, forest residues (such as dead trees, branches and tree stumps), yard clippings and wood chips and garbage may be used as biomass.




Heat Pumps

Geothermal and Air to Water Heat Pumps. Heat Energy is widely available in the ground, air and water around your house. These natural sources of heat are constantly replenished by the sun, wind and rain. A heat pump system will harness these free and renewable energy sources to heat your home and supply hot water at a very low cost. The role of the heat pump is to 'pump up' heat from a low temperature source (e.g. the ground or the air) and release it at a higher temperature into your central heating system.



Hi Efficiency Gas and Oil Boilers
Typically, the “as new” efficiency of an oil or gas boiler over 15 years old would have been less than 80%. It’s present efficiency today, due to wear and tear is unlikely to be greater than 70%.

The current range of boilers available today will have efficiencies greater than 90%. This represents an operational improvement in efficiency of up to 20 percentage points

Increasing the operational efficiency of your boiler by this amount represents an actual fuel saving of more than 25%.  In other words, by replacing an older, low efficiency boiler with a new, high efficiency boiler, you can cut your fuel bills by a quarter.

So, replacing old boilers makes good sense for three reasons:
Significant fuel cost savings with can only increase as energy prices escalate.
Improved reliability and safety.
And now, with the new Home Energy Savings scheme, you could even get a grant to help cover the cost of boiler and heating control upgrades.

Underfloor Heating
In a hot-water system, warm water is circulated through pipes or tubes that are laid into the floor (usually a solid-screeded floor, although joist-based systems also work well).

Gas, oil, solid fuel, or electric-resistance hot-water boilers can be used as the source of heat for any underfloor heating system, as can a number of other technologies. Condensing boilers and ground-coupled heat pumps are particularly well-suited as the large radiating area of underfloor heating systems allows them to operate in their most efficient manner. Underfloor heating can be run at as low a temperature as 30 °C (86 °F), allowing a heat pump to run at a coefficient of performance in excess of 4.0, compared to less than 3.0 with the high temperatures needed 75 °C (167 °F) for use with small wall-mounted radiators. The critical factor for achieving a high coefficient of performance is to reduce the "uplift" or delta-Temperature needed between the heat source and the heat sink.
